CEMENTING-IVJIACHINE.

Specification of Letters Patent.

Patented Feb. 8, 1916.

To all whom it may concern:

Be it known that we, EDWARD Enronson and JOHN W. Coseaovn, citizens ofthe United States, residing at Beverly, in the county of Essex and Stateof Massachusetts, and at Medford, in the county of Middlesex, in theState of Massachusetts, respectively, have invented certain improvementsin Gementing-Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like referencecharacters on the drawings indicating like parts in the several figures.

This invention relates to machines for applying coating material tostock and is herein illustrated in connection with a machine forapplying cement to pieces of fabric which are to be used to linetheuppers of boots and shoes. In machines of this class it is common toprovide a cement applying roll of comparatively large diameter uponwhich the fabric may be lightly laid, nap side down, and from which saidfabric may be removed to be placed upon a vamp or other part of theupper of a shoe. Itis desirable to coat the nap surface only of thefabric with just suiiicient cement to cause it to adhere to the leatherso that the nap may form a flexible connection between the leather andthe body of the fabric, the body itself not being wet with the cementand consequently not being stiffened when the cement has set. i

One of the principal difliculties which has arisen with machines of thisclass has been that the parts of the machine have become more or lesscovered with thickened cement mixed with particles of lint or otherforeign matter. To prevent this, doctors, scrapers and strainers havebeen used; but owing to the tendency of the cement to become gummy whenexposed in small quantities to the air and to the fact that a certainamount of lint is transferred from the fabric to the machine, it isnecessary to clean the parts of the machine at intervals.

The general object ofthe presentinvention is to facilitate thiscleaning; and to this end one feature ofthepresent invention consists ofa readily removable receptaole-upon which are mounted the doctor, thescraper, the strainer and the cement supplying roll. It is thus possibleby pulling the receptacle from beneath the cement applying roll toobtain ready access to the various parts of the machine.

In machines of this class the bearings of the cement supplying roll areparticularly troublesome, and a. further feature of the inventionconsists in a machine of the class described of open-sided bearingscarried by the cement receptacle in which the trunmons of the supplyingroll are received. -With this construction, when the cement receptaclevention is embodied; Fig. 2 is a detail per-.

spective of one end of the cement receptacle and the bearing which ispivoted thereto; Fig. 3 is a perspective of an end of one of thetrunnions of the cement supplying roll; and Fig. 4 is a perspective ofthe machine, the base having been broken off.

Slidably mounted in the base 1 of the machine and held in adjustedposition by set screw 3 is a column 5 to the upper end of which is fasta supporting table 7 having a flat upper face upon which the cementreceptacle 9 rests. This table is designed to permit the application ofheat and for this purpose has a socket to receive a heat unit 11 whichmay be connected with any suitable source of electricity. The table alsocarries a U-shaped length of steam pipe 13 which may be connected to asource of steam; and either or both methods of applying heat may be usedas desired.

The cement applying roll 15 is fast to a shaft 17 which is rotatablymounted in uprights one of which is shown at 19. To the shaft 17 is fasta gear 23 which is driven through a pinion 25 from a driving shaft 27,said shaft being arranged to be clutched when desired to a pulley 29 bythe manipulation of a hand lever 31. a The clutch itself will not bedescribed further since the details of its mechanism form no part ofthis invention. In order to supply cement to the applying roll 15 acement supplying roll 33 is arranged to contact at its upper portionwith the under portion of the applying roll 15 and to turn with itslower portion dipping into the cement in the re ceptacle; and thissupplying roll is formed at each end with raised portions 16 whichdetermine the thickness of the coating of cement carried by said roll.

In the operation of the machine the applying roll 15 is rotated in acounter-clockwise direction as viewed in Fig. 1; and in order toregulate the thickness of the coating of cement which 1s carried by saldroll, a

doctor 3-1 is fast upon studs 35 carried bythe receptacle 9. To theright hand stud,

as viewed in Fig. 1, is fast a lever 37 is received in an arc-shapedgroove, V-

shaped in cross section, said groove being formed in a projection of onewall of the re ceptacle 9. In order to remove from the applying roll thelint and dirt which accumulate upon it, a resilient scraper 17 islocated as shown in Fig. 1, said scraper being fastened to one wall of araised compartment the bottom of which is formed by a strainer 49.,

In machines of this class it is very desirable that ready access to thevarious parts beprovided in order that the cleaning of the parts may befacilitated. The mounting of the doctor, the scraper and the strainerupon the cement receptacle, as has been described above, permits readyaccess to these parts since the receptacle is so mounted that when thelatch 52 is swung from the posi tion occupied in Fig. 1 to that occupiedin Fig. 2 the receptacle may be pulled out from beneath the applyingroll 15. In order that the supplying roll 33 may be removed from thereceptacle, said roll is provided at each end with a trunnion 51 whichis received in an open-sided bearing 53. Each bearing is pivoted upon ascrew 55 which is threaded into an end wall of the receptacle, saidbearing being urged upwardly about its pivot by a spring 56, see Fig.4:, which rests upon an adjusting screw 57 and supports a plun ger 59.The screw, spring and plunger are, seated in a suitably shaped socket ina boss on the receptacle 9, and over each plunger projects an ear 61which is integral with the of lint is distributed about the machine,

and this lint is particularly troublesome when it gets into the smallspace between the ends of the trunnion 51 and the adjacent walls of thebearing 53. In order, then, to force such lint out of said space andthus prevent interference with. the rotation of the supplying roll, eachtrunnion is provided at its end with flaring grooves 65 which cross theradii of said trunnions. In the illustrated machine these flaringgrooves are straight and are arranged obliquely to said radii. Thedirection of rotation of the trunnions is indicated in Fig. 1, fromwhich it will be clear that any-lint which may be wedged against the endof a trunnion will be worked outwardly to the periphery of saidtrunnion. In order to permit the escape of such lint, a passage 67 isprovided in the lower wall of each bearing 53. l/Vhen,

therefore, a piece of lint gets wedged in be tween the end of a trunnionand the adjacent wall of the corresponding bearing, it will be workedoutwardly by the grooves 65 and finally forced into the passage 67.

In order'to protect the cement from dirt and dust, a cover 69of sheetmetal may be hung upon a flange of the doctor 34 as shown in Fig. 1. Asecond cover 63 is pivoted at the rear of the receptacle andextendspartially over the compartment which contains the strainer.

In the operation of the machine power is applied to the shaft 27, andthe applying roll 15 is thereby rotated slowly, said roll rotating thesupplying roll 33 and causing the last named roll to lift cement fromthe receptacle and deliver it to the applying roll. Il l1en it isdesired to clean themachine the latch 52 is turned down to the positionshown in Fig. 1 and the receptacle is pulled out from beneath theapplying'roll. The supplying roll is then lifted out. The various partsof the machine which are liable to be covered with more or less hardenedcement and bits of lint are thus readily exposed so that said parts maybe cleaned very quickly. After the cleaning has been accomplished, thesupplying roll 33 serves as a stop to limit the inward movement of thereceptacle, .and when the receptacle has reached its inward position thescraper 4:7

and the doctor3l are in operativerelation to the applying roll 15.

Although the invention has been set forth not limited in the scope ofits application to the particular machine shown and described.
